My interest in boat engines is limited to their running well enough and
efficiently enough to get me back to shore. On my current boats, I
perform a brief pre-operation checklist and start them up. I keep them
spotless. When the hourmeter says it is time for them to be serviced,
they get serviced. So far the relationship has worked out well. I don't
perseverate on them.

This past weekend, I changed the oil on my smaller tractor. I looked
carefully at the discarded oil as I poured it into the jug I'll use to
take it over to the disposal facility. I checked the plugs, too. Should
I have changed them?

Now, tell me, what kind of engine do I have in my tractor? Gas or diesel?
